calling include from an included file

Question

So, examining this directory structure

• /include_one.php
• /include_two.php
• /directory/main_file.php

A

Answer 1

The include path is relative to the first file in the include chain.

A good way to ensure the correct include path is to always include from the document root.

This is done like this:

include $_SERVER['DOCUMENT_ROOT'] . '/folder1/folder2/includetwo.php';
